Graph of delta K values to determine the ideal number of groups present in 5 sheep ecotypes.
The rate of change in the log-likelihood values between the number of genetic populations, K, for K = 2 to K = 9, showing that the value of K with the greatest support is K = 5.

Clusters inferred from STRUCTURE at K = 2–5.
The cluster membership of each sample is shown by the colour composition of the vertical lines, with the length of each colour being proportional to the estimated membership coefficient.
